摘　　要：单原子催化剂(SACs)是一类仅含有孤立的单个金属原子作为催化活性中心的催化材料.由于其具有100%的原子利用率、独特的化学结构及优异的催化活性等优点,近年来在电化学催化和电能转换设备领域备受关注.本文综合评述了单原子催化材料的设计理念、合成方法和表征方法,同时对其在氢电化学循环(电解水制氢和氢燃料电池领域)的实际应用进行了系统介绍,并对单原子催化材料的研究和应用前景进行了展望.Single-atom-catalysts(SACs) represents a family of catalysts that contain single metal atom as the catalytic active site,which is widely used in the field of electrochemical catalysis and electric energy conversion equipment due to its advantages high atomic utilization efficiency. In this review,the design rationale and synthetic strategies of SAC catalysts are reviewed. Their implementations in the hydrogen circle,including the electrolysis of water and hydrogen fuel cells,are systematically analyzed,along with the prospected main challenges and the future research of SACs.
